COMBINED ARCH STRUCTURE

The utility model relates to the field of construction, in particular, to the original arched structures of predominantly small-sized prefabricated buildings for various functional purposes.

Known arched structures with high arches of circular or close to shape 1, made predominantly through masonry.

The disadvantage of such structures is the great complexity in their construction.

An arched structure 2 is also known, including arches mounted on a foundation laid along the upper zone of the arches and secured through the tension system above the base of the arches with an awning fence, the lower end of which is attached to the side elements placed between the arches and supported on the foundation, while the side elements are made concave and located on the inside of the structure, and the lower end of the tent fence is attached to the upper part of the side element with the formation of a freely hanging cavity filled with cargo.

The disadvantages of this structure are the design complexity, short service life and low heat-shielding performance.

Of the known arch structures, the closest in technical essence to the proposed technical solution is a prefabricated arch structure 3, including arches supported on the base by balancing supports from the upper, lower balancers and trunnion, cross-ties in the form of flexible belts and a coating shell laid on the external surface of the arch with the upper and lower balancers rigidly

ARCH STRUCTURE

The utility model relates to the field of construction, in particular, to the original arched structures of predominantly small-sized prefabricated buildings for various functional purposes.

Known arched structures with high arches of circular or close to shape 1, made mainly by masonry.

The disadvantage of such structures is the great complexity in their construction.

An arched structure 2 is also known, including arches mounted on a foundation laid along the upper zone of the arches and secured through the tension system above the base of the arches with an awning fence, the lower end of which is attached to the side elements placed between the arches and supported on the foundation, while the side elements are made concave and located on the inside of the structure, and the lower end of the tent fence is attached to the upper part of the side element with the formation of a freely hanging cavity filled with cargo.

The disadvantages of this structure are the design complexity, short service life and low heat-shielding performance.

Of the known arch structures, the closest in technical essence to the proposed technical solution is a prefabricated arch structure 3, including arches supported on the base by balancing supports from the upper, lower balances and trunnions, transverse ties in the form of flexible belts and a coating shell laid on the extruded surface of the arch with the upper and lower balancers rigidly

M.C. EV04 1/32

interconnected and supported on a pin, rigidly fixed by the ends at the base, and flexible belts are attached to the lower balancer with the possibility of tension.

Such arched construction also has inherent disadvantages noted in general, due to the complexity of the design, short service life and low heat-shielding performance.

The technical result, which consists in eliminating the aforementioned drawbacks, is achieved in the proposed arched structure, consisting of arched arched elements connected to each other, resting on the base, while arched arched elements are made of wooden beams, each of which is made of arched segments, sequentially joined together , each arcuate segment is made of a rectangular wooden blank, on the lateral surfaces of the arcuate segments there are pinches and grooves along the edge angular trajectories, the end surfaces of the arcuate segments of the beam are located under

angle a 10 ° -g 90 ° to each other and they are filled with end spikes and grooves, and

arcuate arched elements are interconnected through circular joints "spike groove.

At the same time, waterproofing gaskets are located between adjacent arcuate arched elements.

The essence of the utility model is illustrated by drawings, where:

FIG. 1 shows a perspective view of a part of a prefabricated arched structure, assembled from five arcuate beams;

FIG. 2 shows an arched structure (in cross section) with support on the base;

-Fig. 3 illustrates the main steps in manufacturing arcuate segments of an arcuate beam;

A prefabricated arch structure consists of arched arched elements 1 (Fig. 1a) connected to each other, supported by a base 2, for example, a horizontal overlap of a small-sized building 3, shown in FIG. 1b in cross section.

For the erection of an arch structure, a combined profiled timber bar is used, which is made from rectangular blanks 4 (see Fig. 2a).

Using milling, the side surfaces 5 and 6 of the rectangular blanks of size B x D (in section AA) are trimmed along concentric circular paths and an arcuate segment 7 is obtained (Fig. 2b).

The trimming of the arcuate segments 7 of size b x D (in section BB) of the beam is carried out by milling with the formation of the end surfaces 8 and 9 with the docking elements 10 and 11 located on them (Fig. 2b, c). At the same time, jointing elements 12 and 13 are also formed under the spike-groove connection on the upper 14 and lower 15 surfaces along a circular path and gluing the beam elements along the connecting surfaces (Fig. 3).

In this case, the end surfaces of the arcuate segments of the beam are milled under

angle a to each other (drawing the angle CC is not marked).

Stiping at the ends to ensure a pinch-tsaz connection and gluing can be carried out for any number of arched segments 7 of the beam.

In the subsequent technological processing, the external surfaces of the jointed arched segments of the beam 7 are prepared (for example, stripping) and a sticker is made on the surface of the beam of the protective layers 16 and 17 with overlapping zones of the arched segments of the beam 7 (Fig. 3).

In this case, arched beams 1 are formed, from which an arched structure is erected (Fig. 1).

31Ш} О and% To build the structure to be erected in height,

sequential joining of the beams 1 along the lateral surfaces with the provision of a tongue-groove connection and gluing. At the same time, for reliable sealing and protection against moisture, waterproofing gaskets (not shown in the drawings) are inserted between the side surfaces of adjacent beams 1.

The proposed structure can be used for arched coatings of various building structures.

When using such arched structures, additional work is not required on the external and internal surface finishing, as well as on the insulation of rooms.

Wooden arcuate beams can be made on woodworking machines using standard and non-standard tools, forming a production line, and using well-known materials: wood of various species, finishing materials (veneer, plastic, etc.).

Thus, the proposed technical solution allows arched structures with a smooth surface.
